FIG. 2 is a perspective view showing the outer appearance of the front side of a passenger car. A turn signal lamp 3 is attached to a recess 2 of a bumper face 1. As shown in FIG. 3, the turn signal lamp 3 has a mounting structure that simplifies the work so that it can be mounted by being fitted from the outside of the bumper face 1.

FIG. 4 shows a conventional structure in which the mounting work is simplified. Flange-shaped ends 1a and 1b are provided on a bumper face 1 forming a recessed portion 2, and a tapping screw is provided at one end 1a. 4 was screwed in, and at the other place, the end 1b of the bumper face was held between the leaf spring 6 projecting from the lamp housing 5 and the locking rib 7, and fixed at two places in total. . The leaf spring 6 is formed in a dogleg shape and is provided with a protrusion 6a.
The turn signal lamp 3 is positioned and pinched by the end portion 1b by being fitted into the mouth hole 8 formed in b.

[0005]

By the way, according to the above-mentioned conventional structure, since the work of mounting the lamps on the bumper can be carried out from the front face of the bumper face, the lamps can be easily mounted on the bumper before being assembled to the vehicle body. Of course, it is also possible to mount the bumper on the vehicle body before mounting the lamps. However, when fitting the lamps, the positional relationship between the leaf spring 6 and the mouth hole 8 cannot be visually confirmed from the outside, so the lamps should be carefully inserted from a certain direction, and the leaf spring 6 should be projected to feel the response and sound. It was necessary to confirm that the portion 6a was fitted in the mouth hole 8 before performing the work.

For this reason, not only the time required for the mounting work of the lamps is long, but also it is necessary to spend a sufficient time for the confirmation after the mounting work. Further, there is a possibility that a vehicle may be improperly installed due to a slight carelessness, and therefore improvement has been desired.

Therefore, an object of the present invention is to provide a structure for mounting a lamp or the like on a bumper in which the end portion of the bumper face can be held and fixed by an elastic spring and a locking rib easily and reliably in a short time. To do.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is a bumper for lamps which is fitted and fixed in a recess integrally formed on the surface of the bumper face. In a mounting structure for a lamp, a housing of a lamp having a projection, an abutment surface defining the vehicle width direction, and an elastic spring formed by forming the projection on a rear surface, and the housing abutting the abutment surface. Of the abutting portion that defines the position in the vehicle width direction of the housing, and the introduction portion that is formed in a tapered shape and that is combined with the protruding portion that defines the vehicle up-down direction and the front-rear direction of the housing and the mouth hole into which the protruding portion is fitted. It is a structure for mounting a lamp or the like on a bumper, which has a bumper face provided.

Further, the present invention is characterized in that the contacted portion and the introduction portion are integrally formed.

[0010]

According to the above-described means of the present invention, when the lamps are inserted into the recessed portions of the bumper face, the vehicle width direction of the lamps is caused by the contact between the contact surface of the housing and the contacted portion of the bumper face. Since the lamps are regulated (positioned) and the vehicle vertical and longitudinal directions of the lamps are regulated (positioned) by the combination of the protrusion of the housing and the introduction portion formed in the bumper face in a tapered shape, the lamp with respect to the bumper face It is possible to easily and surely determine the attachment position of the class in the three-dimensional direction. In addition, since the introduction part is formed in a tapered shape, even if there is some positional deviation when inserting the lamps, it will eventually be guided to the correct mounting position.
The protrusion of the elastic spring is securely fitted into the mouth hole provided in the bumper face.

Since the abutted portion and the introduction portion can be integrally formed by utilizing the conventional bumper face structure, no major structural change is required on the bumper side.

[0012]

An embodiment of the present invention will be described below with reference to FIG. 1A is a cross-sectional view corresponding to FIG. 4 of the conventional example, FIG. 1B is a cross-sectional view taken along the line AA of FIG.
(C) is an enlarged view of a main part showing a state before mounting the lamps.

In FIG. 1A, flange-shaped end portions 1a and 1b are provided in a recessed portion 2 formed in a bumper face 1, and one end portion 1a extending in the vehicle width (left and right) direction is provided.
Is used for fixing by tapping the tapping screw 4 as in the conventional example. The other end 1 extending in the front-back direction
In b, a protrusion 8 of an elastic spring, that is, a protrusion 6a of a leaf spring 6 formed in a dogleg shape is fitted at a predetermined lamp mounting position, and a tip portion is notched in a wide trapezoidal shape of the inlet portion. And an introduction portion 11 (see FIG. 1B) formed in a tapered shape are provided. Further, in this embodiment, since the outer surface 13 of the end 1b is used as the contacted portion for positioning the lamp housing 5 in the vehicle width direction, the introduction portion 11 and the contacted portion are integrated with the bumper face 1. It has a structure formed in.

On the other hand, on the rear surface of the lamp housing 5, the above-mentioned separate leaf spring (imaginary line shows a natural state) 6 is projected, and the locking rib 12 is projected by integral molding. . As shown in FIG. 1 (c), the locking rib 12 has an abutment surface 14 that abuts on the outer surface 13 of the end portion 1 b that is the abutted surface and positions in the vehicle width direction, and an introduction portion. Protrusions 15 are provided for positioning in the up-down direction and the front-rear direction by combining with 11. The projecting portion 15 of this embodiment is a trapezoidal portion that substantially coincides with the introduction portion 11, and the entire front end surface 16 is brought into contact with the butting surface 17 of the introduction portion 11 to perform vertical and front-back positioning. Therefore, the tip surface 16
It is preferable that the length of is the same as or slightly smaller than that of the abutting surface 17. However, the projecting portion 15 does not necessarily have to be trapezoidal so as to substantially match the introduction portion 11, and may be, for example, a rectangular shape in which the length of the tip end surface 16 is equal to or slightly smaller than the abutting surface 17. In addition, 18 in the figure is the introduction part 1.
A guide sloped surface that is cut out in a taper shape from the inlet portion 1 toward the abutment surface 17, 19 is a sloped surface that forms a trapezoidal protrusion 15, and 20 is provided at the rear end of the locking rib 12. It is a guide slope in the vehicle width direction.

The operation of mounting the lamps having the above-mentioned structure on the bumper will be briefly described below.

The turn signal lamp 3 on the left side of the vehicle body, which is assembled in a separate process, is fitted and fixed in the recess 2 of the bumper face 1 so as to be pushed in from the front. At this time, it is not necessary to carefully check the insertion position of the turn signal lamp 3 with respect to the recessed portion 2, and if a slight displacement occurs, it is corrected as follows.

When the guide inclined surface 20 of the locking rib 12 hits the end 1b of the bumper face 1, the end 1 on the fixed side.
The turn signal lamp 3 is slid to the right with respect to b and is pushed in, so that the turn signal lamp 3 contacts the outside surface 13 of the contacted portion.
4 are brought into contact and abutted. At the same time as this,
After the tip end surface 16 of the projection 15 enters the wide entrance of the introduction portion 11 and is guided by the tapered guide inclined surfaces 18 formed above and below to correct the position in the vertical direction, the tip end surface 16
Contacts the abutting surface 17. As a result, the contact surface 14 contacts the outer surface 13 in the vehicle width (horizontal) direction with respect to the fixed end 1b, so that the tip surface 16 contacts the butting surface 17 in the up-down direction and the front-rear direction. By doing so, positioning can be performed easily and accurately. Therefore, the protrusion 6a of the leaf spring 6 can be securely fitted into the mouthpiece 8 that is aligned at a predetermined mounting position, so that the elastically deformed leaf spring 6 and the locking rib 12 are indicated by the solid line. In between, the end portion 1b of the bumper face 1 is clamped and fixed. After that, if the tapping screw 4 is screwed in and fixed to the end portion 1a as well, the work of attaching the turn signal lamp 3 is completed only by the work from the entire bumper face.

Thus, according to the mounting structure of the present invention,
Since the lamps can be mounted on the front side of the bumper and the positioning function in the three-dimensional direction is provided, the blind alignment and fitting of the base 8 and the projection 6a of the leaf spring 6 are relatively short. Easy and reliable in time.

Although the lamps are turn signal lamps in the above embodiments, they can be applied to various lamps such as fog lamps in other embodiments. Further, in the above embodiment, the elastic spring is the separate leaf spring 6, but in other embodiments, the elastic spring may be integrally formed with the lamp housing. Further, in the above embodiment, the introduction portion is provided at the bumper face end portion and the protrusion is provided on the locking rib, but in other embodiments, the contacted portion and the introduction portion are separate bodies. The locking rib may be provided with the introduction portion and the bumper face end portion may be provided with the projection portion. With such a structure, the positioning action in the vertical direction and the front-back direction can be obtained.

[0020]

According to the present invention described above, the work of fitting the lamps into the recessed portion of the bumper face from the front surface and mounting the same can be performed easily and surely by providing the positioning function in the three-dimensional direction. Therefore, it has a great effect on shortening the working time and preventing the occurrence of defective mounting.

Further, since the contacted portion and the introduction portion can be formed integrally with the bumper face, the above-described operational effects can be easily achieved without making a large structural change.
